Mr Henry Thai
    Kocent Optec Limited is our long-term partner. In 8 years of co-operation times we together win many projects. Their fast connector and FTTH drop cable quality are best. Their products are cover my country now.
    Mr Pablo
    I was surprised when i made first order with Kocent Optec Limited in 2014. One container 40GP of GYXTW cable and one container 20GP for fast connector, patch cord and adapter. They finished this order in 2 weeks only. Now we also purchase many type of FDB box and Splice Closure Box from them. Hope we will be stronger and stronger in telecom field.

Product Description



Non Metallic Direct Burial Outdoor Fiber Optic Cable G657a1 Telecom Grade 144 Cores

- GYFTY fiber optic cable is a non-metallic cable used for power transmission system, excessive thunder areas and high electromagnetic interface. Its mainly application is for aerial or duct use. We supply both single mode GYFTY cable and multimode GYFTY cables.
- GYFTY FRP locates in the center of cores as a non-metallic strength member. The cable tubes, which are filled with filling compound, are stranded around the strength member. Then the aramid yarn is applied over water proof material, the cable is completed with a PE sheath.
- GYFTY cables are available from 2 cores to 144 cores. It is used in high-voltage area for long distance communications.
- The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. The cable core is wrapped with the water blocking tape to protect it from water ingress, then the cable is completed with a PE sheath.
